Not only does this go against everything Merit stands for, it's also totally off-topic, and worst of all: it's a Merit source (#2 most Merit sent) doing this.
Idk about Raja_MBZ, Last of the V8s, xhomerx10 but the other 2 guys don't really deserve 30 merits. The ulrich_zh guy posted "nice" thrice just to get more merits. While its a good thing that QA doesn't spend insane amount of time thinking whether or not he should give 1 merit to a user unlike other , QA shouldn't just shove his merits to hoe's out there. I mean, we get it, you are rich, stop showin' off. We don't want a bitcointalk version of Trump(we already have theymos and cyrus), otherwise before you know it, Stormy Daniels would come here accusing you of 
I really don't see the harm done here. It's not like QA was handing out merits to his alt accounts, so he can sell them for more on the open market. Also, @LoyceV the Wall Observer thread has been off-topic for quite sometime. In fact, it is no longer moderated by the staff. It is currently moderated by infofront. But he only deletes some troll posts from time to time.
